Asphalt Surface Preservation

Seal coating creates a protective surface for roadways, retaring the deteriorating effects of weathering, of chemicals used for cleaning and deicing, and of grease, oil and gasoline spills.

Benifits of Sealcoating

Seal coating is of very great benefit in slowing asphalt raveling and the formation of ruts and potholes. The effect of sunlight on asphalt is to dry out the light oils; the effect of oxygen in the air is to oxidize the bitumen.  Together their action produces a chemical change which causes brittleness of the pavement, permitting release of the surface aggregate, no longer held together by its binder.  At this stage of degradation asphaltic concrete becomes water-soluble.  Water from rain or night dew can easily penetrate the surface and cause further deterioration.

Seal Coat Application

A seal coat applied at the time of original pavement installation or before the pavement becomes structurally unsound, by inhibiting the action of atmospheric elements, increases the service life of the pavement.  However, except for the minor restorative effect of slurry seal, seal coating has no repairing effect, and cannot improve a surface which has already been damaged.  (Slurry seal, a particularly heavy seal coating, can fill cracks and small holes.) All asphalt should be sealcoated as needed.

Asphalt Suraface Traction

Highway slurry used for roadways, rougher in texture than parking-area seal coating, provides a rough surface for good traction- especially important for roads which carry high-speed traffic.

Cleaning and Maintenance Asphalt

Seal coating reduces maintenance costs. The absence of exposed cracks and of loose stones and other particles reduces wear and enhances the useful life of cleaning machinery and implements. Since the seal-coated surface is relatively smooth and uniform, it offers less resistance, and less force is needed for cleaning, which becomes more thorough and rapid.

Pavement Appearance

Seal-coating a pavement results in a clean, new look, deepening the surface color. The smooth seal-coated surface is more attractive to pedestrians.

Pavement Safety

Seal coatings eliminate loose stones and aggregate which can contribute to a fall or a turned ankle.  On an unsealed pavement it is not uncommon for a vehicle tire to flip a loose particle into the air; the particle may strike a pedestrian or a window or damage a vehicle's finish.In corporation of selected fine material aggregates into a seal coating during application results in safer, more skid-proof surfaces.  A variety of surface textures may be achieved without impairing the seal coat's effectiveness.

Sealcoating Service Life.

The service life of any seal coating is heavily dependent on type and volume of traffic. Most asphaltic sealing materials have a normal service life of one to three years, depending on quality and quantity used. The service life of fog seals is quite limited from three to nine months.
